cannot add or install addons

[GeorgeB]

So I had to re do my pc, and now the firefox addon website, the addon section within firefox itself only display the site map. Also, NONE of the addons will install for me. Gives me no exact reason as to why. Just tells me it cannot be added.

I have spent the last hour or more researching and trying various "solutions" to no availability. Any help?

Have you tried reinstalling your Firefox or maybe reset Firefox to its default state? Have a try with this link:
https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems

If that doesn't work also, then you need to contact Mozilla for the problem.

Try to uninstall and reinstall your FireFox, it's better to reinstall the latest version of FireFox and to see what will happen next. Good luck!
